摘要： A tracking error signal detector includes: a photodetector (103) for detecting reflected light from an optical recording medium having a servo area provided with a first wobble mark and a second wobble mark; an amplifier (104) for producing a summation signal of the reflected light; a sampling portion (105) for sampling the summation signal; a first arithmetic portion (106) for calculating an extremum of the summation signal in the vicinity of reproduction timing for each of the first and second wobble marks from the sampling values so as to produce first and second extremums; and a second arithmetic portion (107) for producing a tracking error signal that corresponds to a difference between the first and second extremum. The tracking error signal detector can produce a high-accuracy tracking error signal even if sampling is performed with an asynchronous clock relative to the summation signal.

摘要： A wireless communications terminal prevents radio interferences caused by other wireless communications concurrent with a contactless communication. A wireless communications terminal receives, in a contactless communication, a command from a reader/writer via a second wireless communications section, and analyzes the received command. The wireless communications terminal controls a wireless communications control section to deactivate or temporarily deactivate the function of a first wireless communications section depending on the analysis of the command. After the function of the first wireless communications section is deactivated or temporarily deactivated, the wireless communications terminal accesses a memory area of an IC card microcomputer system as specified by the command to perform a contactless communication.

摘要： A digital recording system for stereophonic audio signals is disclosed. Included is an MP3 encoder coupled to an ADC for encoding the two channels of digital audio signals into a compressed data stream. Before being directed into a flash memory for editing, the compressed data stream is split into the original two channels of audio data blocks. An editing device is coupled to the flash memory for block-by-block editing of the stored audio data blocks. On being subsequently retrieved from the flash memory, the two channels of audio data blocks are reformatted into an MP3 data stream preparatory to introduction into an MP3 decoder.

摘要： If a scene specifying button (202) is pressed while a TV program is being viewed (S601), scene specification information including a point in time, a channel, and the like is generated (S602). The broadcast data of a scene corresponding to this scene specification information is retrieved from a related information storage section 404 (S603). The retrieved broadcast data is subjected to format conversion so as to become text data (S604). The text obtained by the format conversion is put into the body of an electronic mail (S605). After a complementary addition is made to the body of the electronic mail as necessary (S606 and S607), the electronic mail which is completed is transmitted to a destination user (S608). This makes it possible to create a mail easily and accurately, so that a communication system that fulfills the necessity of immediate response is realized.

摘要： Via a mobile communication network, a transmission apparatus receives position information representing a current position of a reception apparatus. Based on the received position information, the transmission apparatus generates notice data indicating that it is necessary to correct preprogrammed program information identifying a program which has been preprogrammed for viewing or preprogrammed for recording and being generated at the reception apparatus, and transmits the generated notice data to the reception apparatus. Accordingly, a transmission apparatus is provided which generates information that allows preprogramming of a broadcast program for viewing or recording to be properly performed at the reception apparatus side, or which generates a correct broadcast program table, and transmits the generated information or program table to the reception apparatus.
